Import Tips
• Provide chemical analysis certificate proving alloy content (e.g
• Cr, Mo) without exceeding tool steel thresholds from Chapter 72 note (e)
• Declare exact dimensions; products over 600 mm width shift to different subheadings
• Avoid common pitfall of assuming pickled surfaces are 'not further worked'—pickling is chemical treatment per notes
